Abstract

The invention discloses a welding flexible general assembly precision on-line detection apparatus and method. The welding flexible general assembly precision on-line detection apparatus includes a mounting rack, a state acquisition unit, a precision detection unit and a data processing unit, wherein the state acquisition unit includes a vehicle type induction bolt on a detected unit, and a vehicletype induction proximity switch on the mounting rack through a first support, and is used for detecting the current vehicle type state of flexible general assembly and sending the current vehicle type state of flexible general assembly to the data processing unit; the precision detection unit includes an X direction displacement sensor, a Y direction displacement sensor, a Z direction displacement sensor and a second support, and is used for detecting the distance of the detected unit in the X direction, the Y direction and the Z direction and transmitting the distance to the data processingunit; and the data processing unit is used for processing the detected signals, displaying the result of processing in the mode of graph and data, and sending the result of processing to the welding flexible general assembly control system at the same time. The welding flexible general assembly precision on-line detection apparatus and method can realize automatic on-line detection precision of welding flexible general assembly.

Description

technical field [0001] The invention belongs to the manufacturing technology of automobile welding, and in particular relates to an online detection device and method for welding flexible assembly precision. Background technique [0002] The welding flexible assembly station is used to position the side wall of the body and the lower part of the car. It is a crucial station in the control of the dimensional accuracy of the body. The positioning accuracy and repeat positioning accuracy of the flexible main assembly unit have always been the process technology. focus of attention. However, the current precision monitoring of welding flexible assembly is mainly carried out by laser tracking and joint arm three-coordinate detection. This method has the following problems: [0003] (1) The detection time is long, time-consuming, labor-intensive, inefficient, and affects normal production; [0004] (2) It can only be inspected randomly, and real-time dynamic monitoring cannot be...
